From my understanding, what comes out of your Bialetti will be espresso because it is still a steam-infused preparation. The espresso grind is fine, although you can adjust that for taste as you like. Coarser for a little weaker product, and finer for a stronger.

I was just getting ready to get my "no name Bialetti" out for an affogato de frozen custard spin tonight. So, I think what will come out of mine is, at least for tonight, an "ice cream sauce." :-)

Thanks for the response. Searching a little more online I came across this page from bialetti:http://www.bialettishop.com/BW/Brikka...It's for the Brikka model but suggests "medium to coarse ground espresso coffee". Enjoy that dessert!
